Sara Caldwell, DVM
Practice Owner
Dr. Sara Caldwell grew up in Atlanta Georgia with her mom and step-dad, one brother and a house full of pets. She is the owner of the practice and its primary veterinarian.  She always wanted to be a veterinarian since she was a little girl rehabilitating tiny birds that fell from their nest and putting pretend casts on her teddy bears.  She is thoroughly fulfilled by relieving the suffering of animals and is honored to be able to do so as a livelihood. She enjoys horses, specifically dressage, although she has evented, foxhunted and played polo.  
Her favorite dog breeds tend to be brachycephalic (like pugs and bulldogs) but she has also owned and loved dachschunds, Danes, and heelers. She currently shares her home (and her heart!) with a pug, a Clyde cross horse, and her very sweet small child :)
